A Great Resource

Gmatclub's online CAT exams are worth your time investment. There are are few places available, in my experience, where you can practice very similar GMAT like problems besides the official MBA.com/GMAC practice problems. It is important to practice problems that are very similar to the official problems in order to train yourself to recognize the style, patterns, and content within the Quant section of the GMAT. I would especially recommend taking all 26 Quant tests under timed conditions, especially if you are weak in Quant before buying the 6 available official exams from MBA.com (2 are free the other 2 pairs cost $50 each) Review every problem in detail - notice patterns - IE - train yourself to not make clumsy mistakes by recognizing to test 0 or not to use negative numbers etc). The Quant exams will help you build confidence, help you to spot "exception/constraints" that are being asked for that can be easily overlooked, help with timing, and just overall give you a very realistic sense of what to expect exam on test day. It took me 20 exams with detailed review to be able to established my orientation. I can't overestimate the value in the adaptive nature of these exams. Each exam provides detailed explanation for each problem - Bunuel is huge contributor to the GMATCLUB forum and his expertise is super valuable. I have tried several top GMAT programs (Gmatpill, Manhattangmat, 1% GMAT, E-E-gmat, Dominate the GMAT, GMAC/MBA) and would rate the Quantitative material (26 exams) 2nd behind the official GMAC. The Verbal section (9 practice exams) I would just say if you are looking for practice problems these are just as good as the competition - I would focus especially on critical reasoning and RC for practice.. The SC in the Verbal portion ...if you are at an 80% rate on SC and aiming for 90% plus - quality SC is extremely important - and so the best place for closing that gap to reach 90% plus SC rate is with the official questions. There are a number of questions in SC that seem to deviate slightly from the official GMAC content which may not reflect actual ability (but I have seen SC questions from top 5 competitors whose questions "deviate" even more. Nevertheless, I still feel that reviewing SC is very helpful. GMAT Club thank you for your content. Good Luck to all taking the GMAT.
